The custom of the husband cutting the thread tied to the bride on the wedding night

Question:
The questioner from Sudan (Yusuf A. A.) says: We have some customs in marriage, and that is after the marriage contract is concluded between the man and the woman, which is called: cutting the tie. The tie is a thread or a belt tied around the middle of the bride, and this is done on the wedding night. The husband is asked to cut that tie or belt. Is this permissible? We ask for clarification, may you be rewarded.

Answer:
This is a custom among people. If it is their custom, cutting it does no harm, and if he does not cut it, it does not harm the marriage. However, their intention is that it is a sign that he has entered upon her... So if he does it in response to them and to please them, that is better.
